Researchers have identified an immune pathway that promotes the formation of a cell that can develop into new tissues and organs.

(Minds) Bioquark, a biotech company based in the United States, has been given the go-ahead to begin research on 20 brain-dead patients, in an attempt to stimulate and regrow neurons and, literally, bring the patients back from the dead.

Artificial mouse embryos grown from stem cells in a dish could help unlock secrets of early development and infertility that have until now evaded us.

Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. This deterioration is the primary risk factor for major human pathologies, including cancer, diabetes, cardiovascular disorders, and neurodegenerative diseases. Aging research has experienced an unprecedented advance over recent years, particularly with the discovery that the rate of aging is controlled, at least to some extent, by genetic pathways and bioch...

One of the key questions in biology is to identify how tissues are repaired after trauma and understand how stem cells migrate, proliferate, and differentiate to repair tissue damage. Researchers define, for the first time, the changes in the stem cell dynamics that contribute to wound healing.

A new study led by scientists at The Scripps Research Institute (TSRI) and the J. Craig Venter Institute (JCVI) shows that the act of creating pluripotent stem cells for clinical use is unlikely to pass on cancer-causing mutations to patients.

Scientists reveal that the combination of two molecular signals determines which cells that have already differentiated can regain their stem cell properties.

Human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells represent a potential alternative source for red blood cell transfusion. However, when using traditional methods with embryoid bodies, ES cell-derived erythroid cells predominantly express embryonic type ɛ-globin, with lesser fetal type γ-globin and very little adult type β-globin.

Muscle stem cells (MuSCs) exhibit distinct behavior during successive phases of developmental myogenesis. However, how their transition to adulthood is regulated is poorly understood. Here, we show that fetal MuSCs resist progenitor specification and exhibit altered division dynamics, intrinsic features that are progressively lost postnatally.
